a citizen of theUnited States, residing at ,Olev'elamL-in the county ofCuy'ahoga and State of Ohio, have invented. certain new and usefulImprovements in Carbureters, of which the".,fOllQWing is aspecification,

reference being bad thereinfto the accompany ng drawing.

- -Tl11S inve tron relates to improvements in earbureters, andparticularly pertains to that type of carburetor in which there are twoseparate air passages, each having a separate oil supply, whereby thereare two separate carburetingpass'ages;

The present improvements, as embodied gwebs 5 and 6. The inlet ends ofthese passages'are each provided with inlet passages, 7, and theiroutlet ends 8 are each provided with eontrollingthrottles or valves 9and 10.

No claim is made herein for the valve mechanism here shown anddescribed, as this will form the subject matter of a divisionalapplication.

Having thus described this invention, what is claimed and desired to besecured by Letters Patent, is

A carbureter having two I carbureting passages, a vertically arrangedfluid chamber located between said passages at a point intermediate theends of the horizontal passages, the fluid supply chamber having aseparate exit passa e extending into each air passage, one end 0 theassageshaving air inlet passages at one si e of the supply chamber andthe other ends having throttles located at the opposite side of thesupply chamber. 1
